One of the most common benefits of piezoelectric material(https://tinyurl.com/yny7xwb4) is ceramics, which are quite strong and stiff under tension. It does help in solving the problem by sandwiching the ceramic to form the composite that districts the strain. That is why it helps reduce the likelihood of cracks in the ceramic. A light tap or simple drop of the raw piezoelectric wafer will crack that up. However, if you use the packaging for Piezo, then that will not cause any problems.
